Ortho-planar linear spring

Hi, I've been experimenting with a number of options for printing flat spring structures and after reading around I designed this sprung platform. The main reference for this work is this article: Parise, J.J., Howell, L.L., and Magleby, S.P., “Ortho-Planar Linear-Motion Springs,” Mechanism and Machine Theory, Vol. 36, Nos. 11-12, pp. 1281-1300, 2001. So in their terminology this is a Tri1-1S ortho-planar linear spring.

Printing lots of these leads to a continuum robot design which I intend to make in the longer-term once I'm happier with it. This follows the ideas of Qi et al within the article : P. Qi, C. Qiu, H. Liu, J. S. Dai, L. Seneviratne and K. Althoefer, “A novel continuum-style robot with multilayer compliant modules,” Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), Chicago, USA (2014) pp. 3175–3180.

Hope you have fun with it!

(Edit : I've just uploaded the scad file for the spring)
